7 Claims.

This invention relates to a new and improved wire spool holder.

The main object of my invention is to provide a wire spool holder ofsuch construction that it is adapted to receive and hold wire spoolshaving varying lengths of cores.

Another object is to provide a holder which will automatically centerthe wire spool when the device is assembled.

Another object is to provide a holder of such a construction that thebinding wires for the spool may be left in position so that they may bereconnected to secure the spool, if it is desired to remove it from theholder before the wire has 5 been entirely used.

Other objects and advantages relate to the size, shape and arrangementof parts, all as will more fully appear from the following descriptiontaken in connection with the accompanying drawing in Which:

Figure 1 is a perspective view of my holder.

Figure 2 is a section on line 22 of Figure 4, showing a wire spool inposition on the holder.

Figure 3 is an exploded view of my device.

Figure 4 is a section on line 44 of Figure 2,

with the wire spool removed.

My device is used to hold wire spools as l in which the wire 2 is woundon a core 3 usually of cardboard.

Before use, the wire 2 is held in position on the core 3 by a plurality,in this case shown as six, of binding wires 4, which are passed throughthe core 3 and secured together on the outer surface of the coiled wire2.

I provide a pair of opposed circular side plates 5 and 6 having centralapertures and inwardly extending inwardly tapered collars 7 and 8extending inwardly from the edge of the central aperture in such sideplates 5v and 6.

Side plate 5 and its collar '7, and side plate 6 and its collar 8 areprovided with radially extending grooves as 9 and 10 in which thebinding wires 4 are seated when a wire spool is in position in thedevice.

An end plate 11 has a central hub 12 adapted to seat in the collar 7 ofside plate 5. A tubular post 13 extends outwardly from the center of hub12, the aperture in post 13 being continued r through the hub 12.

00 The end plate 11 and the hub 12 are provided with radially extendinggrooves 14 in which are seated, when the device is assembled, the ridgeswhich are formed in side plate 5 when the grooves or channels 9 areformed therein.

The end of post 13 is threaded and. a key-way 15 is provided therein.

A second end plate 16 is formed with a central apertured hub 17 adaptedto seat in collar 8 of side plate 6. Hub 1'? is provided with an in- 1wardly extending key 18 adapted to enter the key-way 15 in post 13 tohold the parts against relative rotary motion when the device isassembled.

As may best be seen from Figure 2, I provide 5 in hub 17 a springpressed ball 19, which has a portion normally extending outwardly aslight distance beyond the outer face of end plate 16 for a purposehereinafter to be described.

End piece 16 and hub 17 are provided with a plurality of radiallyextending grooves 20 to receive the ridges formed on side plate 6 whenthe grooves or channels 10 are formed therein.

For the purpose of locking the parts after they have been assembled, Iprovide a knurled nut 21 having on its inner face a plurality, in thiscase shown as six, of recesses 22.

For the purpose of providing a convenient means for tightening nut 21, Iprovide on its periphery, a plurality of spaced recesses 23 into which anail or rod may be introduced to aid in manipulating the nut 21.

When it is desired to place a wire spool 1 in my device, the end plate11 is inserted through the central opening in side plate 5. The core 3of the wire spool 1 is then placed over the post 13 and on the taperedcollar 7. The tapered collar 8 of side piece 6 is then placed over thepost 13 and into the core 3. The end plate 16 is then placed in thecollar 8 and over the post 13 with the key 18 in registration withkey-way 15. The nut 21 is then threaded on the post 13 and turneddownwardly to draw the assembled parts together. The nut 21 passes overthe spring pressed ball 19 until it is moved downwardly to its finalposition and is then left in position with the ball 19 seated in one ofthe recesses 22, so that there may be no possibility of the nut 21unscrewing from its locking position.

The collars '7 and 8 being tapered, they will automatically center thecore 3 as they are drawn together.

The post 13 is of such a length that wire spools having cores ofdifierent lengths may be assembled in the device.

When the wire spool 1 has been placed in position in the holder in themanner just described, the binding wires 4 are cut and their loose endsare passed outwardly through apertures 24 and 25, which are provided inthe outer ends of channels 9 and 10 respectively.

In this position, the'wires 4 will not interfere with the running of thewire 2 from the spool 1, but they will be available for re-binding thespool 1 if it is desired to remove the same from the holder before allof the wire 2 has been removed from the core 3.

I also prefer to provide an aperture as 26 in one or both of the sideplates 5 and 6 as a convenient means for securing the end of the wire 2when the same is not being unwound from the core 3.

The ridges on the outer faces of side plates 5 and 6 being seatedrespectively in the grooves 14 and 20 in the end plates 11 and 16, suchparts will be held securely against relative rotary movement.

Furthermore, end plates 16 being keyed to post 13, it will be heldagainst relative movement with respect to end plate 11. Thisconstruction insures a rigid assembly with all the parts held securelyagainst relative movement.

Although I have shownand described a specific structure and form andrelation of parts as/ an embodiment of an exemplification of myinvention, it will be understood that I do not desire to restrict myselfto the exact size, shape or relation of parts, as various changes may bemade within the scope of the appended claims.
